Patent 1\To..2,432,540, granted December 16, 1947,,

The. particular instrument shown isdesigned'.

"for receiving any six different stations in any intent'and'broad scopeof'the' invention as here inafter defined and claimed.

Fig. 1 in-the drawings is a frontelevatio'n'ofa radio receiver having features of the invention incorporated therein;

Fig: 2-is anenlargedverticalsectional View as on substantially the planeofline 2-2'of Fig. 1', and showing one of the station'selectingslides actuated to effect theturningon' ofara'dio receiver and to accomplish wave band selection,

tuning of a station in the'waveband selected and'setting of the-volumecontrol for'that particular station;

Figs. 3 8.110114 are broken horizontal sectional three different waveJoands.v provided with siX difi'erent control units,.numbored I to 6. Each of these control units is shown as having a volume control knob l3, and

in backof that a tuning knob. l4, and a wave 1 band'selecting lever [5. These may have suitable dials or markings such as those indicated, including the designations A, B and. C, whichin 7 this case, may 'be considered .as representing the short wave, broadcast and frequency modulation.

positions of the wave band selecting levers.

Details .of the adjusting and setting mechanism are illustrated in Fig. 2, where the volume control knob I 3, is shown fixed on the outer end of a shaft l6, rotatable within the tubular shaft H,

which in turn is rotatable within an outside,

sleeve or tubular shaft I8. The tuning knobv I4, is mounted on the outer end of the inner tubular shaft, back of the volume control knob and the wave band selecting lever 15, is shown fixed to the forward end of the outer tubular shaft back of" the tuning knob.

All three concentric shafts are mounted on and carried'b'y a slide l9, in this particular instance", by journalling' the forward end of 'the'inthe: inner end. portionof the slide; At'its inner Accordingly, it is,

- 3 end, the slide is shown as branched in three longitudinal, straight and substantially parallel forks 22, 23, 24. The upper and lower of these are shown used for supporting and guiding the:

inner end of the slide in openings 25, 26, provided in the partition or bridge wall 21. The

outer end of the slide is shown riding in a guide slot 28, in the front wall 29, of the chassis or base structure.

A spring 3!), surrounding the intermediate branch or fork 23, by engaging the partition wall 21, thrusts and normally holds the slide outward in the position indicated in Fig. 4.

The inward movement of the slide is utilized for effecting the setting or actuation of two or able linkage 34a, may be employed for impart-j ing adjustments to a tuner or other instrument,

in accordance with the setting of the camv 32.

The central pivot portion of this cam as shown in Fig. 2,, is adapted to pass through the opening 35, in the rocker, to enable the horns at 36, 3 at opposite ends of the same to engage the face of the rocker and tip it into different angular positions.

Adjustments of thetuner cam 32,:are effected in the present disclosurefrom a worm 38, on theinner end of the inner tubular shaft IT, in

engagement with a corresponding worm gear 39,,journalled on the slide at 40, and carrying a pinion 4!, in mesh with an intermediate or idler pinion 42, engaging the gear segment 43, on the back of such cam.

A rocker such as may be, employed for effecting volume control adjustments is illustrated at 44, pivotally mounted forengagement and operation by. a second camv 4'5, centered on the.

lowerjend of the slide at 4B.

,A volume control unit such as might be adjusted from the second rocker 44, is indicated in outline at 41, the rocker being extended at 48, Fig. 7, or the like, for effecting operation of such volume control. a

The setting of the second, in this case, volume control cam 45, is shown as efiected through a system of irreversible gearing, similar to that.

for the tuner, consisting of a worm gear 59, fixed on the inner end of inner shaft l6, and engaging a corresponding gear 50, journalled on the slide at 5|, and having a pinion 52, in mesh with the.

gear segment 53, on the back of the cam.

The rocker for effecting the third function, in this case. the wave band selection, is indicated at 54, pivotally mounted at 55. Fig. 6, below the slide, for actuation by a third cam 56, pivoted on the lower, forward portion of the slide at 51.

and adjusted to and held in any one of the three wave band selecting positions by a link 58. The latter. is shown pivotally connected at its lower endwith the cam; at 59, and as having a rack 50, on the upper, side portion of the same, engaged by a pinion or projecting gear teeth GI, on the side of the outer tubular shaft l8. This spur gear connection between the tubular shaft and link, serves to maintain this cam adjusting link in position between the face of the slide and 7 This rocker is indi-j the adjoining side of the tubular shaft. The end of rocker 54, may directly connect with the wave band selecting switch 19, as indicated at 80, in Figs. 6 and 10.

In similar manner, the assembly of the tuning and volume adjusting members serves to interlock and maintain those parts in proper relation. The outer tubular shaft l8, supported on the inner tubular shaft, is positioned longitudinally between the angled bearing lug 20, at the front and the worm 38, at the back. This worm is fixed on the intermediate tubular shaft I1, and thus acts as a stop to prevent that shaft pulling forward. Inward movement of this shaft is stopped by engagement with a spacer washer 62, between the two worms. The inner worm 49, is fixed on the inner shaft I6, at the forward side of the bearing lug 2|. Consequently, this worm and the shaft to which it is fixed, are located and held in position by the act of assembly and serve in turn to hold the other parts in proper relation.

The adjusting means for both the upper and the lower, the so-called tuner and volume control cams, are irreversible, in the sense that they will be held by their adjusting gearing in the positions in which they have been set by the tuning and volume control knobs.

Similarly, irreversibility is provided for the lower, forward, wave band control cam, in the illustration, by means of a spring pressed ball detent 63, at one side of the outer shaft member 18, engaging in properly positioned detent seats 64, in the opposing face of the front bearing lug 20, of the slide.

The spring detent 63, is shown as housed within a laterally projecting lug or key 65, on one side of the tubular shaft it, which will enter any one of. the three notches (it, in the front plate 29, of the chassis. to lock the selector in either the A. B or C position. This interlock serves to prevent accidental shifting of the wave band selector, for example, when the slide is in its inward position and the knobs are being adjusted for tuning and volume control purposes. When the slide is in the outward position, Fig. 4, the inner end of the lug 65, will clear the front wall of the chassis and hence at such time, the selector lever l5, may be turned one way or the other to set the wave band selecting cam in any one of its three positions. By engagement in one of the notches 65, on the inward movement of the slide, the key lug 65, prevents any shifting of cam 56, as it strikes the rocker 54. Thus the cam is positively held in its adjusted position during the active part of its stroke. This interlocking arrangement thus relieves the spring detent 63, of any heavy load during the actuating movement of the slide, but the spring detent serves to retain the wave band selecting lever in the selected position, when the slide is out and the selecting lever is unlocked from the chassis panel.

In addition to the three functions described, the slide may be utilized for other, more or less related purposes, such for example, as throwing a switch to turn the receiver on, following a period in which it may have been turned off.

In the present illustration, the slide is shown, having a cam shoulder 61', on the upper edge of the same arranged to ride under and lift a bar 58.

pivotally supported at its ends at 69. This bar is shown as carrying a projecting lever 10, dis posed beneath the core H, of a so-called off magnet 12, and which core is pivotally connected at its upper end with a rocker 12a, carrying the on mercuryswitch 13;. Fig; IL The. switch: throwing bar mayextend' acrossthe". top of all". the slides; so that it will-beactuated-by anyone of them and it is shown as; lightly tensioned: downward'to engage any 'on'eofi thetcams '61; by a spring T4.

Thc'construction of the slide-with spaced. arms- 22, 24, at the inner end of the same, operating upper and lower roc'kers, such" as for 'tuningand: volume control purposes and the cams abelow-and. above the slide, operating in: this case? Wave' bandi selector and switch throwingcrockers; provides: a: balanced construction enabling the Slide: to" smoothly perform these several. operations and enabling a relative arrangement of these parts by'w-hich any desired timingzcf such operations" may beeffected. In the illustration, theicam 61, on top of the slide is positioned to-actuate rocker 68, toithrow'the control switch: to th'e.'on"" posi'-- time before the tuning, volume control or band selecting switches are actuated or fully adjusted. The combination furthermore allowsfor'agroup ing'of the rockers, on difierent centersyaboutithe' slide, as may be necessary to suit different and special requirements of construction, operation" and design.

The operation of the slide or slides maybe" manual-or automatic or partlyiboth. For-manual operation, the slides-maybe simply pushed in' by pressure on the outer button or knob I3 In the case of an automatic receiver, such asillustrated, the" slides may. be actuated by sole noids l5, acting on cores 16, attached to the'inner ends of the slides.

To set the receiver illustrated-to e; desire-dsta tion, it is only necessary to turnthe' lever" l5,.of one of the slides to the "A, B or C position',corr.e'- spending to the wave bandin'whichithati station. operates and to then pushin'that slide and' 'h'oldit so, While turning knob M, to-tune in that par-- ticular station and adjusting knob !3:;. to? the desired sound level;

The rotation of knobs I4 and it, rocks the cams 32 and 45, and these, through their engage ment withrockers 3| and 44, impart-the necessary adjustments to the tuner and volume control, to bring in the desired station atthe'desiredlv0l--- ume. The worm gear actuating connections to" these cams being irreversible; the cams-:will-stay in these adjusted positions for subsequent automatic or manual operations-of the slide. These worm gear connections furthermore are ordinarily sufiiciently close fitting. to insure-continu ing accurate tuning anolvolume control adjustments, but it is contemplated thatif founddea sirable, slack compensating takeups maybe incorporated in the lines of adjusting connections-from the knobs back. to the cams.

If, in the illustratiomthecontrol switch13,, is in the on position when a slide is actuated then the cam on the upper edge of. thatslide, will merely lift the rock-er 68; If however,.the receiver was off prior to such.slid'e.operation,. the rocker 68, will have the effect of: raising the core l'l, and rocking the controlswitch intolthe on position. The forward end of the cam 61, serves in the illustration as astop shoulder Til, engageable with the front wall of the chassis to limit outward movements of the slide, as in Fig. 4.

While generally preferred to havethe slide perform all four necessary functionsof turnin'g'the set on, selecting the wave band, tuning and'adjusting the volume, it is recognized that insome casesand particularly for the'more' simple'and inexpensive receivers; some oneor 'moreof these 6 particular. functions and the parts neces'sary" for: that. particular function or functions may be omitted.
